Reacher fans are celebrating after it was announced which book in the best-selling series would be the basis of the upcoming season 3.

Based on the Jack Reacher book series by Lee Child, the TV series stars Alan Ritchson, 41, as the title character, a self-proclaimed hobo and former U.S. Army military policeman with formidable abilities.

The second season hit screens late last year and quickly broke records for Amazon Prime, becoming its top title of the year in terms of total viewers across all series and films globally.

Last month it was also renewed for a third season.

Now it’s been announced Reacher’s next outing will be based on the 2003 novel Persuader.

While season one centred on Child’s debut novel, Killing Floor, which was published in 1997, the second season jumped ahead and depicted storylines seen in 2007’s Bad Luck and Trouble, which was the 11th book in the series.

The show’s star has now announced the next season will centre on the seventh book.

Sharing the news on Instagram, Alan said: ‘Here comes the big reveal. This year’s book for Jack Reacher takes place in Maine. Persuader is one of the best books there is. I can’t wait for you to see this season.’

The plot synopsis for the novel teases that ‘when Reacher witnesses a brutal kidnap attempt, he takes the law into his own hands. But a cop dies. Has Reacher lost his sense of right and wrong?’

Soon after fans shared their thoughts on social media.

‘Knowing that Prime Video is basing season 3 of Reacher off Persuader, I am beyond excited. The opening blew my mind, and the antagonists are just as awesome. Can’t frickin wait for this one!’ Colton Steiner posted on X.

‘Absolutely fantastic choice, cannot wait,’ Dean Plumley shared.

‘Persuader was the first Reacher book I ever read. The end of Chapter 1 was so so good it had me hooked instantly. I read nothing else for about 5 years. Can’t wait for this. Lee Child is a genius,’ Simon Higgins added.

Before Alan stepped into the shoes of the beloved character, Tom Cruise previously played Reacher in two movies, which were released in 2012 and 2016.

However, after watching the show, fans said the Hollywood heavyweight was the completely wrong casting choice, mainly due to the fact he didn’t fit the character’s profile.

‘Really enjoying Season 2 of Reacher as much as Season 1, intelligent and cleverly written. Alan Ritchson is a physical force of nature, much more suited for the role of Jack than Tom Cruise ever was,’ someone shared on Twitter.

Another added: ‘It’s fantastic and entertaining and far closer to the books characters than the Tom Cruise movies ever were. Let’s keep the Reacher train rolling.’
